![]()
On the number line shown, is zero halfway between r and s ? (1) s is to the right of zero. (2) The distance between t and r is the same as the distance between t and -s
- A
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
- B
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
- C
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
- D
EACH statement ALONE is sufficient.
- E
Statements (1) and (2) TOGETHER are NOT sufficient.
答案选的c,我选的B
因为说t r之间的距离等于t与-s的距离,那么首先s本来在t左边的,r也在t左边,则-s在s右边,0则应在s与-s之间,不解啊,求大神解惑
